    • A tongue squeezer includes a cylindrical roller operably mounted on one end of a pivot arm to pivot the roller between a "working" position spaced vertically above a second roller, and an "open" position spaced upwardly away from the second roller. A weight is attached to the pivot arm to bias the first roller downwardly towards the second roller to thereby squeeze a meat product directed between the first and second rollers. A second pair of rollers is operably mounted downstream of the first pair of rollers, with a third roller mounted below a fourth roller. The fourth roller is mounted on a second pivot arm with a weight attached thereto, to apply a biasing force to squeeze the meat product as it is directed between the second pair of rollers, from the first pair of rollers.
